Aluminum bags: aluminum bags, also known as moisture-proof bags, aluminum bags features: anti-static, anti-magnetic interference and moisture-proof function, there will be some light through, but can also play a dark role for the electronics industry, Size can be customized according to customer requirements. Printable surface. Foil bag production process simple and complicated production process, the whole production process: aluminum ingot smelting - casting - cold rolling - intermediate annealing - cold - foil stock - roughing - in rolling - - Finishing (doublet) - cutting - finished aluminum foil annealing - Compound - bag - foil bag finished - packaging. In this process, the wool is from the beginning to the machined aluminum foil prime the whole process, and then the composite bag. Production of aluminum foil bag enterprises in order to save costs and time, usually choose direct purchase aluminum foil, then bag composite materials. Vacuum bags and bags of ordinary by comparison, has a relatively superior performance, both to extend the shelf life of goods, but also to ensure its flavor intact. This is because the bag has a special functionality. The vacuum bag must have a very good sealing properties, namely air and moisture barrier properties, the barrier of the ingredients are water, oxygen and carbon dioxide, so that goods in a completely isolated environment protected, this high barrier made of co-extruded film, a relatively stable nature
